NARROW-WARE LOOM.

Serial No. 407,571.

T 0 all whom it may concern:

Be it known that we, ADOLPH WIDMER` and SAMUEL WIDMER, citizens of the United States, residing in Paterson, Passaic county, New Jersey, have invented a certain new and useful Improvement inNarrow-WareLooms and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon which form a part of this speciiication.

This invention relates to looms and particularly to ribbon looms and it has for its object to provide an improved means for operating the shuttle-driving rack, whereby to secure a smoother action of saidrack and a material reduction of vibration in the loom and at the same time render the parts capable of adjustment, notwithstanding such conditions as irregularities of floor surface, so as to insure their proper coperation with each other at all times.

rlhe invention will be found fully illustrated in the accompanying drawings, wherein,

Figure 1 is a side view of so much of the improved loom as involves the present invention; Fig. 2 is a plan view of substantially what is shown in Fig. 1, portions appearing in section; Fig. 3 is a-vertical sectional view, slightly enlarged, taken in the lane of a certain rock-shaft r; and, Fig. 4 is a iletail of a portion of the means for effecting the movements of said rock-shaft.

In the loom frame a is journaled in the usual manner the crank shaft b carrying gear wheels the nearer one of which appears in the drawings and is marked c. An auxiliary frame d projects from the side of the loom frame a. and may be described as follows: This auxiliary frame comprises a stand e which is arranged parallel with the side of the loom frame, the braces and the brackets g, g', h and i. The braces f are bolted to the frame a, and at their outer ends are formed with vertical slots j through which and horizontal slots 7c of the stand e extend the bolts l. The slots j and le allow a vertical and horizontal adjustment of the stand and braces relatively to each other, so that the auxiliary frame may be adapted to various irre ilarities in the floor surface on which the oom rests.

The bracket g comprises a horizontal portion m and two downwardly extending legs n which are set in vertical grooves o in the front face of the stand e and are secured to the latter by the bolts p which project through slot g in the stand e and thus permit vertical adjustment of the bracket g. The bracket g is formed with a bearing portion gz for a rock shaft r and with a depending portion g3 which is secured by bolts s to the stand c; said bolts extend through vertical slots gi* in the bracket g allowing vertical adjustment of said bracket.

t is a shaft which is journaled in the bracket g, extending through a vertical s lot g5 in the bracket g, and also ournaled in a vertically adjustable bracket u secured to the frame a; this shaft carries the gear v which meshes with a gear w on shaft b, and also a cam x. The horizontal portion m of bracket g carries the studs y which roject i rearwardly and carry anti-friction ro ers z. On these rollers runs a horizontal movable rack 1 having slots 2 receiving the rollers and an intermediate slot 3 through which shaft t projects, the studs having shoulders 4 and washers 5 which insure a true parallel movement of the rack with respect to the side of the loom frame. The rack carries the rearwardly projecting studs 6 on which are arranged anti-friction rollers 7 receiving between them, and bearing against the peri hery of the cam x. The rack meshes with a pinion 8 on the rock shaft 1, the latter also carrying a two-armed crank 9, which crank and the pinion hold said rock-shaft against longitudinal movements in its bearing. The

batteri, marked 10, is carried by the layswords 11 arranged on the shaft 12 rocking in the frame a and bracket i.

13 designates the rack arranged on the batteri and adapted to actuate the shuttles 14 by the means and in the manner well known. The bracket i. is fork-shaped and is attached to the stand c by the bolt 15 arranged in the slot 16 of the stand so that the brocket is adjustable. The bracket h is arranged in the horizontal groove 17 in the face of the stand c and is secured to the latter by the bolt 18, which passes through a frame a are journaled the fast and loose pulf leys 3l and 32, 33 beinO a gear which rotates with pulley 3l and meshes with gear c. The

ower is taken into the loom by means of a lielt which may be shifted from one of the pulleys 31 and 32 to the other by a belt shifter 34 carried by a rock shaft 35 journaled in bearings 36 in the bracesf and carrying an o erating handle 37. 38 designates one of t e pitmen connecting the ybatten with the gear c, whereby the batten is oscillated from shaft b.

The operation of the loom is as follows: When the pulley 31 is rotated, it operates, through gears 33, c, w and v to rotate shaft t and consequently the cam x. Said cam thus reciprocates the rack l which acts through i'nion 8 to rock rock-shaft 1" and thus oscilate the crank 9. rl`he crank, to which the straps 23 are connected in the manner already described at opposite sides of its fulcrum, thus pulls on one strap while it gives way on l the other, thereby reciprocating the rack.

At the same time the batten is being reciprocated through the itman 38. In order to secure the equalize movements of the rack in each direction, the pulleys 2()d on bracket 71,

' may be adjusted vertically so as to bring them in the same horizontal plane in which, in the setting up of the loom, shaft t may come, the studs 2S being of course adjusted with the same purpose in view. Likewise, other parts of the auxiliary frame d may be adjusted with reference to each other so as to secure the proper cooperation of the parts and adapt the mechanism to various irregularities in the floor surface and other condi- .rocking structure with the shuttle driving rack, substantially as described.

2. ln a narrow-ware loom, the combination of the frame, the lay or batten structure, the shuttle-driving rack arranged in said lay structure, a rocking structure, the crankshaft', means for transmitting the power from the crank shaft to said rocking structure comprisinga rotary shaft, a cam on said rotary shaft, a rack controlled by the cam and a pinion engaging the rack and carried by said rocking structure, and flexible connections connecting said rocking structure with the shuttle-driving rack, substantially 'as described.

In testimony that we claim the foregoing we have hereunto set our hands this 13th day of December, 1907.
